HEATER on FUMER. l

Application filed February My invention relatesto heaters and fumers andhas for its object the provision of an electric fumer of improvedstructure for heating, vaporizing, or fuming fuel oils, or otherliquids, or fluids. Another object is to provide an improved fumer forfuming comparatively heavy fuel oils of low volatility, and to providean efficient fumer in which the electric heating element issubstantially protected from oxidizing fluids, and its endurance therebygreatly prolonged.

In the drawings, Fig. 1 is a central vertical longitudinal section of afragment of a fuel manifold for an internal explosion engine, showing incentral vertical section my improved fumer positioned therein. Fig. 2,is a central horizontal section through said fumer. Fig.3, is a top planview of an absorbent element, or refractory sponge, forming part of saidfumer. Fig. 4 is a central vertical section of said sponge. Fig. 5, is aside elevation of a dry chamber jacket.

In the drawing, 1 is a fuel manifold having an enlarged chamber or catchbasin 1 formed thereon or secured thereto, preferably adapted to beclosed at its outer end by a cover or plug 2 and gasket 2. Ex-

tending through said plug into the reduced I of a recess 2* formed inits inward portion 2 end, is an electric binding post 3, insulated fromsaid plug in any suit-able manner or by any suitable means, as by mica,gasketsi.

Upon the inward end of said post and in electric communication therewithis an elec tric high resistanceelement of any suitable.

structure or material, as a carbon pencil or rod 5, preferably providedat its opposite end with a metallic conducting cap 5*. Closelysurrounded said element 5 is a sleeve (3 of suitable refractorymaterial, preferably of non-porous insulating character, as ce ment. p

Extending over sailcap and sleeve is a close fitting vertically ribbedmetallic jacket 7, preferably of copper, in electric communication withsaid cap or the upper end of said rod and extending downward into theenlarged portion of said recess 2 Said jacket is preferably provided atits lower end with an outwardly directed annular flange 7 extending tothe side walls of the enlarged portion of said recess. A sealing ring 8of any suitable material is preferably pressed down upon said flange inthe space be- 13, 1926. Serial No. 88,155.

tween said jacket and the side walls of the enlarged portion of saidrecess, to prevent leakage of moisture from said recess t0 the interiorof said jacket, or below said flange. Said ring is preferably ofelectricity conducting material, as copper, and adapted to improve theelectric communication between said jacket and said plug, constitutingan electric ground for an electric circuit in which said rod isincluded.

Surrounding said jacket and spaced therefrom and extending from saidring' t0v a plane a short distance above said jacket is an exteriorsleeve 9 of any suitable material, preferably of brass or copper.

A moisture absorbing element 10 of any suit-able refractory material,preferably asbestos fibre, is positioned'in the space be tween saidjacket and said exterior sleeve, and is adapted to contact with theoutwardly directed ribs on said jacket and with the wall. of saidexterior sleeve and to extend from said ring to a plane a short distancebelow the upper end of said jacket. Said absorbing element is preferablypressed into cyl indrical form before being assembled in. the. fumervSaid exterior sleeve is provided with an intake port 9 intermediate ofits ends, and-said absorbing body or cylinder also preferably has anintake port 1O formed therein adapted to register with the intake portin said exterior sleeve. 3

A screen 11 of any suitable material or struct-ure, preferably ofcement, is preferably extended across the open upper end of saidexterior sleeve.

An exhaust port or ports 7* are preferably formed in said jacketadjacent to the upper end of said sleeve 6, to prevent the accumulationof any gas pressure which might form in the chamber or contents withinsaid jacket.

Said rod and binding post and jacket and plug are embodied in anysuitable electric circuit with any suitable source of electricity, as abattery 12.

In operation, the heavy liquid particles or globules of fuel drawn fromacarburetor, not shown, into said manifold by the suction of enginepistons, not shown, allwell known to the art, or condensed from moisturein' the manifold when the engine is cooling, will drop into said catchbasin and flow through the intake portin said exterior sleeve into saidabsorbing element and thereby into contact With the highly heated Wallsof said jacket by Which said liquid particles Will; be

fumed, the fumes will be conducted upward by the grooves between saidribs andv will flow out of said fumer through said screen and into saidmanifold, whence they will be drawn into the cylinders of the eng ne mproper condition for use. The upper end of said fumer preferablyextendsslightly above the floor of the body portion of said manifold soastoprevent flooding theupper or exhaust end: of'said absorbent body andavoid-any danger of the fumes being re-condensed' by an overhead floodof liquid.

Said invention is especially effective, use
